Details from a State Police supplemental report reveal that a New Orleans man killed after his vehicle jumped a curb and catapulted onto the roof of a machinery shed in Old Jefferson four months ago was intoxicated.

Louisiana State PoliceA Honda Civic driven by David Medrano, 21, struck a median curb on Jefferson Highway and landed on top of a bus stop and machinery shed in front of Ochsner Medical Center on July 1

David Medrano, 21, had a blood alcohol content of 0.15, well over the legal limit of 0.08, when he died in the single-vehicle crash during the early morning hours of July 1. Authorities had to extricate him from his Honda Civic, which landed on top of the shed/bus shelter in front of Ochsner Medical Center in the 1500 block of Jefferson Highway, according to Trooper Melissa Matey, spokeswoman for Troop B.

State Police did not perform a reconstruction of the accident. But the follow-up investigation determined that alcohol impairment, fatigue and speed played a role in the wreck, Matey said.

The report states that Medrano was headed eastbound on Jefferson Highway in the far left lane when he hit the curb of the grassy median just east of Betz Ave, according to Matey. The car then veered right, back across all three lanes of eastbound Jefferson Highway.

The car then continued into the grass on the right side of the roadway, striking a historic marker that was mounted into the ground with concrete, Matey said. That hit put the car into a counterclockwise rotating flip across the sidewalk. The vehicle flipped and spun for about 45 feet before touching ground again, based on tire marks in the earth.

The contact with the ground sent the car flipping into the air for another 20 feet until it landed again in a patch of shrubs, Matey said. From there, the car vaulted 10 to 15 feet into the air for a distance of 17 to 25 feet and landed on top of the shed.

Because of the rotation, Matey said investigators were not able to analyze the vehicle's speed. But based on reports from eyewitnesses and the force necessary to rip the history sign from its concrete mooring, State Police believe the vehicle was traveling about 60 to 70 miles per hour.
